Abstract: 412,522. Fuel-injection pumps. FUSIONMOTEURS, Boulevard Gallieni, Rueil-Mal. maison, Seine-et-Oise, France. Feb. 12, 1934, No. 4565. Convention date, Feb. 16, 1933. [Class 102 (i).] In a fuel-injection pump the spill port k in the plunger e is uncovered during the discharge stroke by a sleeve f, which moves with the plunger under the action of a spring l, but is retarded at high speeds by the braking action of fuel in the suction chamber a. The chamber is provided with a byepass o, controlled by a needle-valve o<1>, and a byepass p with a checkvalve p<1>. The tension of the spring l is adjustable by means of a pinion n gearing with teeth on a cup m on which the spring abuts. An adjustable stop r is provided for limiting the upward movement of the sleeve f. A flange f on the sleeve f abuts on a disc h<1> on which the return spring h of the plunger acts. Fuel may be supplied to the suction ports c from the space below the disc #<1>. In a modification the braking action of the fuel is exerted on the sleeve f during the downward stroke in a manner similar to that described in Specification 392,867.

Filed: 1941-04-17
Abstract: 546,157. Linear-dimension gauges. BAKER, E. April 17, 1941, No. 5017. [Class 106 (ii)] Relates to precision gauges of the kind in which a slide is movable along a straight bar which usually bears a graduated scale read in conjunction with a vernier on the slide, and consists in doing away with the graduations and vernier and making the slide in two parts relatively movable, the main part being positively arrested on the bar at uniform intervals and the secondary part positively arrested in relation to the main part at uniform intervals which are sub-divisions of the main intervals. A base 10 has two parallel connected columns 12, 14. The slide to which a scriber 55 may be attached comprises a bar 16 bored to slide on the rods 12, 14 with a sleeve 18 on the rod 12. Sliding on the rods 12, 14 above the slide 16 is a carriage 22 having a sleeve 24 on the rod 14. This rod has uniformly spaced at inch intervals conical depressions 28 with which a spring-plunger 30 having a hemispherical engaging head mounted on the carriage is adapted to engage. A thumblever 34 serves to release the plunger. The numbers on the rod 14 are viewed through an opening 25 in the sleeve 24. A wheel 36 is mounted to rotate at the lower end of the sleeve 24 and is provided with ten downwardly extending abutments 38 any of which may engage one of a series of four flat surfaces 44 provided on a wheel 46 and differing in height by 1-40th inch. This wheel rotates on a vertical spindle 48 fixed to the slide 16 and extending freely through the extension 26 of the carriage and being surrounded by a spring 50 abutting between the extension 26 and a collar 52 on the spindle. A nut 54 is threaded on to a screwed portion of the rod 48 and can make one turn only limited by a sleeve secured to the spindle and by the upper surface of slide 16. The opening 25 gives the inches, the opening 40 the tenths or decimals, the four numbers on wheel 46 are 0, 25, 50, 75 representing thousandths, while the numbers on the nut 54 are from 0 to 24 and also thousandths. The dimensions indicated in Fig. 3 is therefore 5.85+.013 or 5.863. Specification 453,405 is referred to.

The chamber and tank are connected by bolts 63 which extend through the tank 23 and through the radial supports 62 of an upper PVC covered shock absorber ring 17, which like a similar lower ring 18 is secured to the chamber 1. Air locks 4, 5 allow access to the chamber. The tank 23 is divided by internal PVC partitions into three compartments each compartment being formed from four PVC tubular elements welded together and being provided with a valve controlled water inlet/air outlet line 31, water inlet/water outlet line 36, and first and second compressed air inlet lines 39, 47 leading from compressed air storage tanks 42, 48. All of the valves in the various lines are operable from within the diving chamber. In operation valves 32 and 37 in the lines 31 and 36 for each of the compartments are opened to flood the tank and cause it and the chamber to submerge. The rate of descent of the chamber is controlled by the admission to the tank of a controlled volume of air through lines 39 and the discharge of a controlled volume of water through lines 36. Further air from tank 48 is automatically admitted to the ballast tank 23 to balance the increasing external water pressure as the chamber and tank sink. The reverse procedure is followed to raise the chamber and tank.
